Abstract
The amounts of organic carbon and several nutrients in litterfall on the forest floor of Quercusforest were assessed for two years from 1998 through 2000 in Mt. Songnisan National Park in Korea. The amounts of organic carbon (C) in litterfall were the highest in autumn with the values of 150.4 g/m2(62.6%) in 1998 and 219.2 g/m2(61.0%) in 1999. In winter, organic C was the lowest with the values of 16.3 g/m2(6.8%) in 1998 and 12.5 g/m2(6.7%) in 1999. It was estimated that the organic C added to forest flor via litterfall was 240.1 gㆍm－2ㆍyr－1and 186.6 g ㆍm－2ㆍyr－1in 1998 and 1999, respectively. The amounts of nitrogen (N) 2(58.0%) in 1998 and 5.2 g/m2(62.3%) in 1999. The amount of phosphorus (P) in litterfall showed its peak in autumn with 0.19 g/m2(52.9%) in 1998 and 0.11 g/m2(52.6%) in 1999. The amount of P returned to forest flor via litterfal was 0.35 gㆍm－2ㆍyr－1in 1998 and 0.22 gㆍm－2ㆍyr－1in 1999. The amount of potassium (K) in litterfall showed its peak in autumn with 0.57 g/m2(53.8%) in 1998 and 0.42 g/m2(55.3%) in 1999. The amounts of K returned to forest floor via litterfall was 1.11 gㆍm－2ㆍyr－1in 1998 and 0.81 g ㆍm－2ㆍyr－1in 1999.
